Abstract:

A general technology for the prediction, evaluation, and specification of closed loop and multiaxis flying qualities is documented. A comprehensive scheme for the classification of precision piloted tasks is presented, and a nonlinear multiaxis pilot model is described. Demonstrations of the aircraftpilottask analysis method are given for a number of precision piloted tasks and aircraft configurations. The analysis method is also applied to a comparison of Gaussian and non-Gaussian Reeves turbulence models, and to a study of the effects of control system lags on tracking performance. Piloted flight simulations were performed to validate all pilot model analyses complete simulation and pilot model data is presented. Specification methods suitable for MIL-F-8785B are suggested in the areas of step target tracking and pilot reserve attention capacity. A computer analysis method is available from AFFDLFGC a user guide, listing, and sample data set are included in the report. Author
